Purpose: Root fracture is a clinical problem which often is difficult to detect and diagnose. As the root fracture detection is based on demonstration of a fracture line or lines, radiographic examination is important. The aim of this study was to compare diagnostic efficacy of direct digital radiography with conventional radiography for detecting experimental root fractures. Materials & Method...

zno and zro2 photo catalysts were synthesized by sol-gel auto combustion method. the products were characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem). structural and morphological properties of nano particles were investigated and the average crystalline size of zno and zro2 was obtained 44 and 51 nm, respectively. also, photo catalytic degradation of nitro phenol f...

Important features of adult neuronal number, location, and type are a consequence of early embryonic events that occur before neurons have differentiated. We have measured cell number during embryogenesis of the rat CNS. Markers that are expressed in the proliferating neuronal precursor are required to study the mechanisms controlling their proliferation and differentiation. By applying immunoh...

Background: Different studies have investigated the association between p53 codon 72 Arg>Pro polymorphism and cancer risk. Because of the lack of consensus of the results in individual studies, we conducted this meta-analysis by pooling all currently available case–control studies to estimate the effect of p53 codon 72 Arg/Pro polymorphism on cancer susceptibility in Iranian population. ...

was drawn to the article by Forestier and Leroux (1935) describing the new pernasal method of administration of lipiodol for visualizing the bronchial tree, we have adopted this method in a modified form in a large number of cases with very satisfactory results. We were successful in all the sixty cases of our series except in one, where the patient, in spite of our best efforts, swallowed the ...

Arginyl dipeptides like Arg-Ser, Arg-Ala, and Arg-Gly are salt-taste enhancers can potentially be used to reduce the salt content of food. The l-amino acid ligase RizA from B. subtilis selectively synthesizes arginyl dipeptides. However, industrial application is prevented by high cost cofactor adenosine triphosphate (ATP). Thus, a coupled reaction system was created consisting acetate kinase (...

Efficient deposition of biomolecules on the surface, maintaining their full activity and stability, is a most significant factor in biosensor construction. For this reason, more research focused development electrochemical biosensors that have ability to electrically detect adsorbed molecules electrode surface with high selectivity sensitivity. The presented aims develop an efficient methodolog...

This paper covers practical study of responses of the systems which are under control. The auto tune proportional-integral – derivative (PID) controller is used for controlling of systems. The auto tune algorithm is implemented using the successive approximation method. The auto tuner has been checked with various plant models in MATLAB environment that causes only minor perturbation on the nor...
